Such as: Code Type: ARM-64 OS Version: iOS 10.2 (14C82). When you need to symbolicate a crash report, check the Code Type and OS Version section. Update: Since iOS 10, iOS firmware are not encrypted, so we can get symbols from firmware now. That's the meaning of this repository, to share these system symbols. That's obviously very difficult to collect them all. A arm64device contains both arm64and armv7s). There are 132 versions from 7.0 (11A465) to 10.2.1 (14D27)(most OS version contains three different type: arm64, armv7s, armv7. That means you need a corresponding device if you want to symbolicate a crash report. It's copying system symbol files from device to your Mac's path: ~/Library/Developer/Xcode/iOS DeviceSupport. When you first connect a new iOS device to Xcode, Xcode will show a loading message: Processing symbol files(after Xcode 9, it's Preparing debugger support for Device). So you can only get SDKs before iOS 7 from Xcode.) ( Update: Actually, since Xcode 6, there is no real device SDK.
#Dmg symbols software
Read this for more details: Xcode software image for user iOS in order to symbolicate iOS calls, Missing iOS symbols at “~/Library/Developer/Xcode/iOS DeviceSupport”. And since Apple replace system framework with tbd files after Xcode7, this trick doesn't work any more. Usually the symbols are part of the latest Xcode release, but Apple doesn't always provide Xcode updates when an iOS version only contains bug-fixes but no API changes.
#Dmg symbols download
You can download old versions of Xcode and pull out the SDK image you need.Apple never offer a website to download these symbols. Most system symbols can only be got from physical iOS devices.If you want to symbolicate system frameworks in your crash report, you need the corresponding system symbols, matching the OS Version and CPU architecture.You may find out that you can't always symbolicate those system code. The problem of symbolicating system frameworks
This crash happened when tap search bar while poping the viewController. We can make out that the problem was caused by UISearchDispla圜ontroller's delegate. So you need to symbolicate these system code. The callstack didn't catch your app's code, it only has code from system frameworks.
