I have same problem in Xcode 11.4 1. Show your YOUR_PROJECT.app folder in Xcode while build success , find Release-iphoneos or Debug-iphoneos folder, select which on determined by your Profile`s build setting. normally we choice Release-iphoneos. 2. Add that path to Instruments in 【Preferences】->【Symbols】 to search YOUR_PROJECT.app.dSYM file.
