iOS (VuforiaSamples-7-1-34) 30MB memory leak

June 5, 2018 - 6:11am #1

ive noticed that when running iOS Vuforia Samples, when i go into one of the samples, say 'Image Targets',

every time i go into the sample and come back out, the memory of the app increases by 30MB! (consistently - using Instruments)

something is not being cleaned up properly - either internally inside the Vuforia lib or the samples code.


please advise on how to resolve this issue as im sure like many people, im using these sample as a guide for my own app development.


XCode Version 9.4 (9F1027a)

iPhoneX iOS 11.4

Hey there,


I'd suggest creating a new thread so I'd be able to better help, but we've seen memory leaks in previous versions of Engine. I'd suggest to upgrade to v10.5.5.


Kind regards,

Best regards,
