The BMW X3 2.0i with a Swift Challenger SE 480 with an actual weight of 1282 kg is in general a good match and suitable for all journeys on all kinds of roads.
The motor preformance of the BMW is in general more than sufficient. And also the weight of the Swift with a User Payload (121 kg in the caravan and 200 kg in the car including passengers), is very good.

BMW X3 2.0i Swift Challenger SE 480
Actual Weights
Swift Challenger SE 480: 1282 kg.
BMW X3 2.0i: 1955 kg.
Noseweight: 75 kg.
Actual weight ratio: 66%.
Performance
The engine's performance is generally good on flat roads (performance score to compare 218 points).
Speeds of 73 mph (118 km/h) to 79 mph (128 km/h) are often quite possible.
There is only moderate power at low engine speeds (score to compare 141 points).
Slightly higher revs (2500 rpm) may be necessary under normal conditions on flat roads.
Acceleration from 0-62 mph (0-100 km/h) is theoretically possible in 20.7 sec.
In the mountains the performance is generally good (score to compare 227 points).
No problems are to be expected on steep mountain roads. Hill starts are possible on steep slopes up to 14%, but do require some experience from the driver.
On motorway inclines higher revs (4300 rpm) are needed.
A speed of 63 mph (101 km/h) is usually possible on most motorway inclines.
Weight
The towing limit of the BMW is more than sufficient (check this in your vehicle documents).
If you passed your driving test after 1 January 1997, a B driving license is enough.
Weight ratio between the laden caravan and the loaded car is 66%. Common in the UK: the weight ratio between the laden caravan and the kerbweight of the car is 74%.
The chance of snaking is small even at higher speeds.
Recommended noseweight is 75 kg.
Stability and safety score to compare is 203 points.
If the caravan starts to snake you should reduce your speed and slow down directly! Lift your feet off the accelerator and brake gradually. Hold the steering wheel into a fixed position.
Conclusion
Performance is more than sufficient.
Safe driving is possible.
It's a perfect match!
Influence of User Payload on stability
Weight distribution and noseweight are vital in obtaining a stable caravan.
