So I want use Leaks to find the leaks in my app. In Xcode, I go to "Product" and then hit "Profile". In Instruments I select Leaks and it starts. My app is starting and Leaks is running. But just as soon as my app is finished starting and I can use it, Leaks stops.

Is there anybody else with the same problem or maybe knows how to fix this?

  • Hm.. It should work fine. Do you still have the problem ? – Legolas Jun 15 '11 at 16:00
  • Yes, but sometimes, like 1 out of 8, it does work. Yet my app launches normally every time. – pkoning Jun 15 '11 at 16:24
  • That's probably a bug that's not your fault. A nasty bug. – Constantino Tsarouhas Jun 24 '11 at 22:04
  • I've been doing a bunch of searching on this and there are various mentions in various places indicating that it's not unique but not very helpful in terms of a fix or workaround. I've replicated it in both XC3.2.6 and XC4.0.2 but I'm not sure if it's only started since I loaded 4.2. I removed 4.2, but you never know what else it changed when it installed that didn't get reverted. – smparkes Jun 24 '11 at 23:29
  • Curious about what devices/sdks you've seen this on. In limited testing, I've only seen it on an iPad 2 running 4.3.3. I haven't seen it on an iPhone 4 running 4.3.3 or an iPad 1 running 4.3.2. – smparkes Jun 25 '11 at 03:09
  • I've tested my app with an iPad 2 (4.3.2), where Leaks stops. I also tested it with an iPad 1 (4.2.1) and it works normally. I haven't tested it on an iPhone though. – pkoning Jun 25 '11 at 21:17

clean project build folder, close XCode IDE and clean MAC Os caches then it should work. if it's an iOS project you have to delete app from simulator/device before re compile it.

I would chose a development profile for all release,debug modes, clean the simulator, clean xcode ,then i would launch instruments

The Leaks instrument seems to close after the app receives lot of memory warnings. Closing all background applications helps.

If you use Cocoapods, be sure, you have unchecked Run script only when installing in Target > Build Phases > [CP] Embedded Pods Framework. Checked this option caused same problem for me.

That was my case. If you're using a real device, make sure you're using a valid provisioning profile (development provisioning profile) and that the device is included in the profile. More detailed explanation here.

I've seen this happen when an incorrect provisioning profile is used when building the app and running on a physical device.

You shouldn't see this kind of error when running it in the simulator - it should work as intended. If you're using the simulator in this situation and are you still seeing this behaviour, I would encourage you to go to http://bugreport.apple.com and file a bug regarding this issue, giving as much detail as you possibly can.

If you're using a physical device, ensure you're using a valid provisioning profile and certificate/key pair and that the device is included in the profile.
