in my AR IOS app when i try migrating from SDK 5.3 to SDK 7.0 those 2 errors in memory C++ appear
The Plugin.h file introduced new methods between version 5.x and 7.x. If you have a closer look at the Xcode error logs, it will tell you which methods you need to implement. Clicking on the error unfortunately jumps into the STL implementation, but the build log actually tells you quite accurate which methods are not implemented.
For reference you could also have a look at our example application and the barcode plugin example.
thank you Andreas i will check them.
