swift - EXC_BAD_INSTRUCTION only in iPhone 5 simulator -

-



running code on iphone 5 simulator throws exception shown in image. running code on of other simulators fine.

i can't spot made mistake in unspectacular line of code. else have problem?

exception shown in xcode

nsinteger (which type alias int in swift) 32-bit integer on 32-bit platforms iphone 5. result of

nsinteger(nsdate().timeintervalsince1970) * 1000

is 1480106653342 (at moment) , not fit range -2^31 ... 2^31-1 of 32-bit (signed) integers. therefore swift aborts execution. (swift not "truncate" result of integer arithmetic operations done in other programming languages, unless use "overflow" operators &*.)

you can use int64 64-bit computations on all platforms:

int64(nsdate().timeintervalsince1970 * 1000)

in case, if string needed:

let lastlogin = string(int64(nsdate().timeintervalsince1970 * 1000))

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
