This is a counterpart to https://github.com/Quick/Nimble/pull/916, which added support for watchOS to Nimble.

Note that this is a draft until a new version of Nimble is released with watchOS support. Until then this points at main.

I'm also not sure if the tests will run on CI correctly because the tests require watchOS 7.4 to run and I'm not sure what version of watchOS the simulators are configured with.

I also found that the tests weren't compiling (using Xcode 13.2.1) so I've updated these too.

Here's a small PR for a bug that I think has just gone unnoticed because we've never used the sectionInset property of the UICollectionViewFlowLayout, and we've never used the contentInset property of UICollectionView.

The issues looks to be that the layout's sectionInset property is applied on a per-section basis, but the collection view's contentInset was not being honoured.

It was also calculated using insetBy(dx:dy:), which will modify the width by -dx * 2, which would double the expected insets.

Motivation and Context

If the simulator is not booted when the status bar is updated it does not do anything and the default status bar is used.

Resolves #19317

Description

xcrun instruments fails with the error "xcrun: error: Failed to locate 'instruments'." This command will boot the simulator if it's not curerntly booted and then wait for it finish booting before terminating.

Testing Steps

Use snapshot while the override_status_bar option is true.

In RSS 2 the description may contain the full text and the content can be omitted when there is not a short version available: https://cyber.harvard.edu/rss/rss.html#hrelementsOfLtitemgt

However a JSON feed will not contain a content_html field when the content is not provided.

This makes it hard to create both a JSON feed and an RSS 2 feed because providing content without a description will create a content:encoded field but not a description field in the RSS 2 feed.

My solution to this is to fallback to the item.description when item.content is not provided and generating a JSON feed.

This PR is to add support for running on watchOS. Since Xcode 12.5 watchOS has been supported but Nimble doesn't currently compile for watchOS.

A new target has been added to the project, along with explicit support in the Package.swift.

I don't believe anything here is a breaking change.

I have a fork of Quick that also supports watchOS. I'll create a PR for that if this PR gets approved and merged.

The package(s) being submitted are:

• VaporDocC

Partial fix for #31

Added to work around https://bugs.swift.org/browse/SR-14103

Overall this is pretty minor but when dealing with a lot of SingleElementSections that are infrequently updated is does start to slow down.

I thought a faster approach would be to use generics on replace(element:) to only check for nil when the value is Optional, but generics don't allow for this kind of overload.

Also added some basic tests. The performance tests show a ~9% performance increase.

Replacing https://github.com/composed-swift/ComposedUI/pull/15

This PR is being used to diff between the OpenNet fork.

Hopefully other PRs will be merged before this (e.g. https://github.com/composed-swift/Composed/pull/21), which should lead to this PR having no changes and purely to ensure some of the history is not lost.

We've discussed returning -1 not being great previously, but now we have the 2.0 branch we can make this change :)

Updated to match syntax in README.md.

Maybe these were intentionally left because the package has a minimum tools version of 4.2?

@bill201207 found that UINib(nibName:bundle:) is a big part of the poor performance when our app launches.

Ultimately batching updates will help with a lot of things like this, but really that'll just be masking some of the performance issues so it's useful to find issues like this now.

This adds the ComposedLayout and ComposedUI packages, which will close #16.

The base for this is 2.0-beta, which we can use for testing new changes, which can also break API.

If you go to the repo settings you can (temporarily) set the default branch to 2.0-beta and we can add a note to the README stating this is the beta release and the stable release is available in the master branch.

Once merged and these changes are made the READMEs for ComposedLayout and ComposedUI repos can be updated to point to this repo and their repos archived.

This is a new type of section that is similar to ComposedSectionProvider, but rather than flattening each of the children in to a single SectionProvider it flattens them in to a single Section.

The ComposedUI side of this has been updated to support multiple cells per section, with a convenience for FlatSection that delegates the calls to each of the flattened sections.

This is a breaking change since the protocol requirements have changed. I have set the base of the PR to merge-all-libraries since that's also a breaking change and this PR relies on those changes.

edit: We've moved to our own fork to allow for more rapid development. The latest changes are in https://github.com/opennetltd/Composed/tree/feature/FlatSection, which will eventually be merged back in to this repo once some of the other PRs/issues have been resolved.

In my open source frameworks I usually use the last major Xcode (currently 11.7), latest (currently 12.3) and latest beta (soon to be 12.4), but this project has only been setup for the latest version of Xcode.

If we feel it's good to run the tests across multiple Xcode versions I have created https://github.com/JosephDuffy/update-xcode-version-action, which we can use to keep the versions in-sync with the versions available as part of GitHub actions.

For now I've removed all use a explicit Xcode versions.

Regression introduce in 1.1.1.

Would occur when a segmented provider was the last child of a composed provider and the selected segment changed.

This could have also been fixed in SegmentedSectionProvider but changing the _currentIndex after the delegate has been notified (which is closer to what ComposedSectionProvider does) but we have nothing in the API contract stating this must be done, so really it's an issue with the caching in ComposedSectionProvider.

These properties are accessed quite frequently and can be cached with a little extra processing.

This is another finding from screens that have a large number of composed sections.

This and https://github.com/composed-swift/ComposedUI/pull/15 seem to be the main areas of performance issues, although that doesn't mean that once these are working and merged we won't uncover more 😅

Thanks to @bill201207 for their contributions to this change.

The idea of this is that without breaking the API the collection view will batch updates.

Inserting a large number of sections is the main area of performance loss we are currently encountering, because the sections are inserted individually and not batched. This change alone has reduce the initial load time of one our screens (which has 100-150 sections added at once) from 30-45 seconds down to less than a second (at least it is not noticeable).

I had created https://github.com/composed-swift/Composed/pull/17 to try and address this, which has the advantage that it would apply to other view types (e.g. UITableView), but I believe does not offer the same performance improvements and it is restricted to a single ComposedSectionProvider.

This is a draft to collect feedback; as you can see there are some TODOs but I think there's enough implemented to provide an overview of the changes that would be required to implement this.

This does not currently work; there are situations that cause the collection NSInternalInconsistencyException', reason: 'Invalid update error. I have some failing tests that demonstrate what the result should be.

When adding a lot of sections (we have a screen which inserts 100~175 on initial load) the performance is quite poor.

Along with the improve-composed-section-provider-performance branch (which I want to fully validate before making a PR) performing these changes in batch helps a lot.

As mentioned in https://github.com/composed-swift/ComposedUI/issues/13 and https://github.com/composed-swift/ComposedUI/issues/8 there are some scenarios where the collection view’s data is out-of-sync with the data in composed.

As mentioned in https://github.com/composed-swift/ComposedUI/issues/13 calling layoutIfNeeded can trigger the data to be in sync again. In this I have added it to mappingWillBeginUpdating(_:) which appears to solve the problem.

It might be needed in replace(sectionProvider:) (because reloadData is called) and/or mappingDidInvalidate(_:) (for the same reason) but I’m still investigating.

I have validated this fix against https://github.com/composed-swift/ComposedUI/issues/8 and it fixes the crash.

https://github.com/composed-swift/ComposedUI/issues/13 still needs to be investigated and may require layoutIfNeeded to be called in mappingDidInvalidate. Marking as a draft until this is checked.

Xcode 12 ships with 5.3 but also drops iOS 8 support. This causes a warning ("The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 14.2.99.")

This is a major API change so is in a v2 branch. If we agree on a direction we could start adding PRs in to this branch.

This change would enable multiple changes to be applied at once, e.g. by requiring balanced calls to mappingWillBeginUpdating and mappingDidEndUpdating and only performing the updates when an equal number of mappingDidEndUpdating calls have been made. This could be a small performance improvement but would also improve animations.

By adding the performUpdate closure the changes to the model layer can be applied only when the consumer is expecting them, e.g. for UICollectionView this would be inside performBatchUpdates and would fix the existing crashes that occur when performing a change when there are pending layout changes.

Some tests and types have been commented out since this is more of a starting point for a discussion around the API than it is a solid implementation.

This is the closest I can see the API being (although it's still a breaking change) but maybe a bigger change would be better.

The biggest PITA is that the sections need to keep track of "current" data (e.g. what's being displayed by a collection view) and the "pending" data (e.g. what's about to be applied). I don't think this adds any memory overhead but it does add much more to the knowledge required when implementing a section.

Changes proposed in this PR

• Fix extraction order of symlinks

Tests performed

• Existing tests
• Extracting the AltServer download from https://altstore.io/

Further info for the reviewer

This needs more tests to ensure full coverage, but also to prove that this was previously broken and is now fixed.

The added function is public because I'm using it to extract a subset of the entries in the archive that contains symlinks.

Open Issues

#185, possibly #62.

These were quite hard to track down since the errors that would occur would often be visual and not a crash, although in some scenarios it did seem to trigger a crash.

I think this highlights the need for a much larger test suite.

Sidebar

It also made me question the insert(_:at:) functions because it's not really clear what the index is. Should it insert it at the index in the context of the sections and providers (as it does now), or just sections?

For example, with:

• Section A
• Section Provider
  • Section B
  • Section C
• Section D
• Section E

If I insert a section at index 3 should it look like:

• Section A
• Section Provider
  • Section B
  • Section C
• New Section
• Section D
• Section E

or

• Section A
• Section Provider
  • Section B
  • Section C
• Section D
• New Section
• Section E

The tests are currently essentially empty but at a minimum this makes sure things compile on Xcode 11.7 and 12.0.

@shaps80 I think this will need updates to the repo settings to enable GitHub Actions.

Introduced in #9. #12 adds GitHub actions to ensure this doesn't occur again.

Previously there was no way to get the index of a child or even know if a Section or SectionProvider is a child of a ComposedSectionProvider.

On top of these functions new insert(_:after:) and insert(_:before:) have been added for convenience.
