FR: Enable Performance session capturing for 100% of users in development

[juliecantin]

[REQUIRED] Step 2: Describe your environment

• Xcode version: 10.1
• Firebase SDK version: 6.5.0
• Firebase Component: PerformanceMonitoring
• Component version: 3.1.1

[REQUIRED] Step 3: Describe the problem

Create a new single-view app in Xcode
Follow the instructions to add Firebase to the app
https://firebase.google.com/docs/ios/setup

Follow the instructions to add FirebasePerformanceMonitoring to the app
https://firebase.google.com/docs/perf-mon/get-started-ios

Launch the app
Wait 12h
Look at the FirebaseConsole and try to access sessions for the performance logs
Sessions are not available, we are advised to update our SDK

Relevant Code:

SampleFirebasePerf.zip

I removed podfiles and GoogleService-Info.plist, you will need to restore podfiles and add your own GoogleService-Info.plist to run the same.

Simply launch the app, wait 12h and look at the data on the console.

Currently the detailed sessions are captured only for a small percentage of the runs. It is quite possible that the runs might not have been picked for detailed sessions capture. Currently we capture detailed sessions only for 1% of the runs (random picks). We are working on enabling this during development time, stay tuned.
