@DTS Engineer Hi, I have run this compilation on M4 mbp. The performance of Xcode 16.3 is excellent. The data is here: Xcode 16.3 (Clang 17.0.0): 16.888s Xcode 15.2 (Clang 15.0.0): 52.073s Xcode 16.3 (Clang 16.0.0): 3m11.971s The new compiler has achieved an impressive speedup. Thank you for your attention to this issue and for delivering such an excellent solution.

Hi, I received an email about this issue today. Some terms are confusing for me. Could someone please confirm my following understanding is correct? As developers, what we should do: We only need to update the CA Trust Store on our servers that communicate with APNs to include the new CA certificate. No changes are required for: The APNS key (.p8 file) The legacy SSL certificates (.p12 file)
