How I convert this implementation using GLKMatrix4 to using CATransform3D

I want to convert GLKMatrix4 and CATransform3D,and I use this method:

 CATransform3D t;
    GLKMatrix4 t2 = *((GLKMatrix4 *)&t);
    t = *((CATransform3D *)&t2);

form: (Convert GLKMatrix4 and CATransform3D).

it work well at 32bit,but can't work in 64bit equipments,and I found the reason is that,GLKMatrix4 is using Float and CATransform3D is using CGFloat,as we know,they are treated different in different bit machines,so this codes can't work in 64bit equipments,here someone can convert it? GLMatrix4 code:

GLKQuaternion   _rotationEnd;
GLKVector2    _translationEnd;
float   _depth;
float   _scaleEnd;

GLKMatrix4 modelViewMatrix = GLKMatrix4Identity;
GLKMatrix4 quaternionMatrix = GLKMatrix4MakeWithQuaternion(_rotationEnd);
modelViewMatrix = GLKMatrix4Translate(modelViewMatrix, _translationEnd.x, _translationEnd.y, -_depth);
modelViewMatrix = GLKMatrix4Multiply(modelViewMatrix, quaternionMatrix);
modelViewMatrix = GLKMatrix4Scale(modelViewMatrix, _scaleEnd, _scaleEnd, _scaleEnd);

How I fix it using CATransform3D?

To solve this generally I suggest you crate the 2 buffers and iterate through them. Try something like this:

    GLKMatrix4 input;
    CATransform3D output;

    GLfloat glMatrix[16];
    CGFloat caMatrix[16];

    memcpy(glMatrix, input, sizeof(glMatrix)); //insert GL matrix data to the buffer
    for(int i=0; i<16; i++) caMatrix[i] = glMatrix[i]; //this will do the typecast if needed

    output = *((CATransform3D *)caMatrix);
