@PeterDaveHello sorry for getting into this PR. What tools did you use to accomplish this, I wonder if we could do the same on this iOS project. https://github.com/TrustWallet/trust-wallet-ios?

[ArtFeel]

@vikmeup You can use ImageOptim. You can even integrate it with XCode.

[vikmeup]

@ArtFeel what do you think about using PDF/SVG instead, which format has better performance and image quality?

[ArtFeel]

@PeterDaveHello You should also disable COMPRESS_PNG_FILES in XCode Build Settings to prevent built-in (de)optimization. Because Xcode's conversion is applied even when it makes files bigger. Otherwise, it does not make sense, except for the size of the source folder.

PNG compression and iOS apps

[ArtFeel]

@vikmeup at this moment I prefer PDF format, you need only one asset for @1x,2x,3x images, and it takes up less space in a source folder. But this is not true vector images on iOS(on OS X it is), XCode will prerender PDF images into multiple PNG on build-time.

So it depends on your app, if it has a lot of images(a game for example), you can optimize image on your own, to reduce IPA size. But if you are not constrained by the app size limit, I think that it's better not to waste time to save 1Mb.

In any case, it is worth to measure it on your own application.
