Apple's CryptoTokenKit is only present in iOS 13.0+ however it exports symbols with availability annotations going back to iOS 10.0. In the Pass app we have a deployment target of iOS 12.0. Apple's automatic weak linking system apparently only looks at the symbol-level availability annotations so it assumes the symbols we use will always be present (even though they won't pre-iOS-13). We can work around this issue by forcing weak linking using the "Optional" framework setting. (Note that this workaround would not work if CryptoTokenKit was used from a third-party swift package.) This is necessary to restore iOS 12 support after #533. For further history see https://github.com/mssun/passforios/issues/539 |
