* Update to Xcode 15
## Summary
We want to make Texture build with recent tools like Xcode 15. Part of this is bumping the minimum supported OS to iOS 14.
I only removed the dead code (i.e. code gated on versions older than iOS 14). There are still some warnings about outdated APIs in use, but they are non-trivial changes to fix.
## Test plan
Run all the examples. Run all the unit tests and make them pass.
* Use Xcode 15.3 so we have 17.4 simulators
* Fixing an asset catalog compiler error when building against iPhone SE
* Fix a couple of file extensions for assets
A couple of PNGs were marked as JPGs
* Try to get CI to work
* update to xcode that exists
* Use a more recent sim; update podfiles not to use github as source
* fix clang 10 error about 10 being extern
* don’t override deprecated method
* Fix tests and snapshot tests
* Exposes a new option in ASImageDownloaderProtocol to retry image downloads
At the moment the ASBasicImageDownloader does not automatically retry image downloads if the remote
host is unreachable. On the contrary the ASPINRemoteImageDownloader automatically retries. Retrying is
something that ultimately clients need to be able to control, for example to fail fast to an alternative image
rather than keep retrying for more than one minute while not displaying any image. This change exposes
a new option in the ASImageDownloaderProtocol to retry image downloads. It also uses this new option
in both ASNetworkImageNode and also ASMultiplexImageNode, setting it to YES to preserve the current
behaviour.
* Fixes a failing test in ASMultiplexImageNodeTests
* Fixes ScreenNode.m
ScreenNode.m is implementing ASImageDownloaderProtocol and needs to
be fixed to reflect changes in the latter.
* Renames AS_EXTERN and ASViewController
To ASDK_EXTERN and ASDKViewController.
This is to avoid conflicting with AuthenticationServices in
Xcode 12
* Fix up examples and docs
* Add bit about updating ASViewController rename
* [License] Simplify the Texture license to be pure Apache 2 (removing ASDK-Licenses)
With permission of the Facebook Open Source team, we are simplifying the Texture
license so that clients can rely on the Apache 2 terms that most of Texture is
already covered by. This means that code originally forked from AsyncDisplayKit
will be re-licensed from "BSD 3-clause + PATENTS v2" to Apache 2 without a
PATENTS file.
After getting confirmation that the updates to these core files look good, we'll
propagate this new license header to all files (in this same PR) and get sign-off
from all parties before landing.
* [License] Update all Texture source files to be pure Apache 2.
* Changelog entry for Apache 2 license update.
* Revert "[License] Update all Texture source files to be pure Apache 2."
This reverts commit ffa0fbbba9.
* [License] Update all Texture source files to be pure Apache 2, maintaining copyrights.
* [License] Update CONTRIBUTING, README, Podspec & Dangerfile.
