Hi, Is there a way to get coordinates (X and Y) of publickey like android ECPublic->ECPoint ?

If not could you add that support?

Encounter the same problem, ask how to solve. How to transform

GMEllipticCurveCrypto* ecc = [GMEllipticCurveCrypto generateKeyPairForCurve: GMEllipticCurveSecp256r1];
ecc.compressedPublicKey = false;
NSData* pkeyX = [ecc.publicKey subdataWithRange:NSMakeRange(1, 32)];
NSData* pkeyY = [ecc.publicKey subdataWithRange:NSMakeRange(33, 32)];
