In the last n seconds mode, there is no data, no lanes, and nothing on the timeline. Instruments is available with Xcode, the complete toolset for building iOS and Mac apps. Instruments 4 is the latest iteration of Apple’s application for dynamically tracing and profiling iOS and OS X code. I see events in the bottom pane in "List: Events" view. Instruments New Features User Guide summarizes some of the new features in Instruments 4. Not seeing any signpost activity is happening in immediate mode and deferred mode. Perhaps it's a provision profile issue? Entitlements? However, I've tried profiling in debug mode with debug provision profile and got the same results. (I'm not using OS_ACTIVITY_MODE = disable but have during the lifetime of this app). Before you can build or run RetroArch on your device, youll need to change the projects code-signing settings to build it with your Apple Developer Team. Apple's developer forums 32 Compile step detail 273 compile time vs. The only thing I can think of at this point is a build setting that could affect it. See debugging Instruments application unit testing code signing 197 ad-hoc. There is no difference between these projects. ![]() I've checked both workspaces and schemes. I can get the config status on both apps' oslog configuration, and there's no difference. However, this same code (integrated into a much bigger app) does not record or display ANY intervals. I see the intervals, signpost icons, etc. The sample code here works in a new project. Lattner also began working on the Swift programming language in 2010, helping to shape it, and is the main author of LLVM. I'm trying to use OSSignposter to capture intervals in our app for use in Instruments. Hes a 12-year Apple veteran who managed the developer tools group that spawned the iPads Swift Playgrounds, as well as Xcode, Instruments, and many debuggers and compilers. How can energy usage data be gathered using Xcode 13 on iOS 15? I would like to determine if this is a bug in my app or a bug in iOS15. Well over a year into production and having sufficient install numbers, I have a feeling that waiting a few days might not do much. When this happens, try checking back in a few days." "In some cases the pane shows “Insufficient usage data available,” because there may not be enough anonymized data reported by participating user devices. When I access the Organizer in Xcode (12 or 13), select an app and click "Energy" for all versions of the app, it shows the following:Īpple's documentation for "Analyzing the Performance of Your Shipping App" says: Instruments no longer includes the Energy template use metrics reporting in the Xcode Organizer instead. Naturally, it's also not possible to profile an iOS15 device with Xcode 12.ĭigging through the Xcode 13 release notes, I found the following: While it is still available in Xcode 12, this template is missing in Xcode 13. Profiling via Instruments using the "Energy Log" templateĪs per the same documentation from Apple described in the section "Use the Energy Diagnostics Profiling Template". However, on iOS15, I can't find any options for logging under Developer or anywhere under settings even when searching. On the device under Settings > Developer > LoggingĪs per Apple's documentation described in the section titled "Log Energy Usage Directly on an iOS Device". Previously, it seems that there were two ways to gather energy usage information: (Note: This app previously showed no issues with battery usage on previous versions of iOS.) If you see inaccuracies in our content, please report the mistake via this form.I'd like to confirm the battery usage of an app I am developing on iOS, specifically on Xcode 13 and iOS 15.
