Area: Something not on this list Summary: Enterprise signed apps that include Swift launch slowly. Steps to Reproduce: Build an Objective-C application, sign with an enterprise profile, and run on a device. Modify the app from above, adding Swift to the project and run on a device. Expected Results: Launch times between the Objective-C and Objective-C/Swift enterprise apps should be similar. Actual Results: The Objective-C/Swift app launches much slower than the Objective-C version of the app. If the apps are not signed by an enterprise profile, the launch time differences between the two versions is negligible. Launch times from a fresh installation (iPad Pro Version 2): Objective-C: ~1.5 seconds Objective-C/Swift: ~6.5 seconds Version/Build: Xcode: 9.2 iOS 11.2.6 Configuration: N/A
