Hello,
Your project is pretty simple for me, but as always the devil is in the details, so I have few questions:
1. What is the reason behind making it in swift? ObjC have better code base and libraries to parse PDF documents (including based on Quartz 2D). I personally prefer ObjectiveC and can't warranty same dev time on swift.
2. Is it possible that source document will have more than one segment of NAV/LOG DATA..SECTOR NOTES ? What we should do in this case and how we'll show this to user?
3. App seems for internal use only, how are you going to distribute it? Do you have apple dev account? (You'll need one to distribute your app to devices)
4. Is there any other functions than opening pdf files? Or simple fullscreen document is enough?
5. What kind of images are you talking about? Default screens? If so its easier to use xib launch screens (we can add logo and text there if you want)
App development will take about a day plus some time to polish things.
It seems you are experienced with freelancer, but usually I suggest to split development to 2 phases, but on this small app we can use only one.
You will get build as soon as I'll make it and if we both will be online (I'm somewhere near your timezone, GMT+7) I think we can fit dev time to one day if everything will be fine.
Please let me know if you have any questions.
Ivan.
