How to split large video as chunks by each size of 5 MB, Swift

I'm working on Video upload process, need to upload large video as multiple chunks. Each chunks should be the size of 5 MB.

Please share the code for converting large video to multiple chunks under size of 5 MB each in swift. Any help is much appreciated

Try this,

    let selectedSize = selectedVideoSizeInMB
    let seconds = durationInSeconds
    print("Size", selectedSize)
    print("Seconds", seconds)
    
    let splitDuration: Int = Int(seconds / (selectedSize/5))
    print("Split Duration", splitDuration)
    
    do {
        let data = try Data(contentsOf: videoUrl)
        let dataLen = data.count
        print("Data Size", data.count)
        let chunkSize = ((1024 * 1000) * 5) // MB
        print("Chunk Size", chunkSize)
        let fullChunks = Int(dataLen / chunkSize)
        let totalChunks = fullChunks + (dataLen % 1024 != 0 ? 1 : 0)
        print("Chunk count", totalChunks)
        
        var chunks:[Data] = [Data]()
        for chunkCounter in 0..<totalChunks {
            var chunk:Data
            let chunkBase = chunkCounter * chunkSize
            var diff = chunkSize
            if(chunkCounter == totalChunks - 1) {
                diff = dataLen - chunkBase
            }
            
            let range:Range<Data.Index> = chunkBase..<(chunkBase + diff)
            chunk = data.subdata(in: range)
            chunks.append(chunk)
            print("The size is \(chunk.count)")
        }
        self.chunksDataArray = chunks
        print("Total Chunk", chunks.count)
    }catch{
        return
    }
